BR-1042MB is a bio-based polyether urethane methacrylate oligomer with a substantial amount of bio-based content and is tin-free. This is a medium hardness version of our biobased products. This oligomer has a good balance of toughness and flexibility. The bio-based backbone, methacrylate functionality and tin-free nature make this an excellent choice for consumer applications with low irritancy.

BR-1043MB is a biobased polyether urethane methacrylate oligomer with a majority percentage (75%) of biobased content. This oligomer provides excellent low-temperature flexibility, elasticity, and excellent dynamic properties and rebound with a lower viscosity versus similar polyether chemistries. The oligomer exhibits a higher degree of heat resistance vs other polyether oligomers. The high biobased backbone and methacrylate functionality make this an excellent candidate for consumer applications with low irritancy requirements.
